Mortar mixing machine



March 4, 1969 A. G. DESKO MORTAR MIXING MACHINE Filed Oct. 20, 1967INVENTOR. ALBEAT' G, DESKO United States Patent 4 Claims ABSTRACT OF THEDISCLOSURE The mortar mixer disclosed herein provides a convenientself-propelled portable mixer and mortar box combination which enablesbricklayers and other such persons to move their mortar from the placewhere the dry mortar is received to the place where the mortar is beingused or where bricks are being laid with the minimum of physical effort.The agitator in the drum mixes the mortar while it is being moved. Themixer is being driven by an engine at the rear of the mixer near thedriving Wheels while the mixing drum and mortar box are at the front.The mortar box support is low enough for convenient use.

This invention relates to mixers and, more particularly, to mixerssuitable for mixing mortar for bricklayers and the like.

It is, accordingly, an object of the invention to provide an improvedmortar mixer.

Another object of the invention is to provide a mortar mixer that issimple in construction, economical to manufacture, and simple andefiicient to use.

Another object of the invention is to provide a mortar mixer with amixing drum, a mortar box support, and engine, along with driver seatand steering wheel, all supported on a self-propelled vehicle.

Another object of the invention is to provide an improved mixingmachine.

With the above and other objects in view, the present invention consistsof the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawing and more particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportions, and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawings:

FIG. 1 is an isometric view taken of the front of the mixer according tothe invention.

FIG. 2 is an isometric view of the mixer taken from the side thereof.

Now with more particular reference to the drawings, the mixer shown hasa frame with drive wheels 11 supported on the back, and front wheels 12.A seat 13 for an operator supported on the frame between the engine 15and the steering wheel 14. The engine 15 is connected by suitable belts,chains, or sprockets or the like to the drive wheels 11 and can bedisengaged from them by a suitable lever, such as lever 16, in a mannerwell known to those skilled in the art. The front wheels 12 are suitablyconnected to the steering wheel 14 so that they can be steered in asuitable manner. Levers 17 and 18 may be connected to suitable belts,sprockets, chains or gears to connect and disconnect the mixing drum 21and its agitator 22 to the engine 15. The mixing drum has an opening atits top, which is covered by a grid 24 and the mixing drum may be tiltedabout its horizontal axis 26 by the lever 23. A mortar box-support isdisposed at the front of the frame slightly above the level of the frontwheel axles and it may support a suitable mortar box 19. The drum willhave suitable lips or chute 26 on it adjacent its openings to guide themortar into the drum and direct the mixed mortar into the mortar box 19.

The steps 27 are provided for a convenient place for the operator toplace his feet while driving the vehicle. A belt guard 25 is supportedon the machine to cover the belt that connects the engine 15 to theagitator 22.

It will be apparent to those skilled in the art that an operator may siton the seat 13 and drive the vehicle by means of the steering wheel 14and the engine 15 and suitable control levers 16 to any suitablelocation; that is, from the place where the dry mortar is received whereit may be emptied into the drum 21 and a suitable amount of water mixedwith it and the mixing operation can take place. The agitator 22 isdriven by the engine 15 as the vehicle is being driven from the site ofreceiving the dry mortar to the site where the mortar is to be used.When the destination for use of the mortar is reached, the operator maythen grasp the lever 23 and rotate the drum 21 about its horizontalaxis, emptying the mixed mortar into the mortar box 19. The bricklayermay then use the mortar from the mortar box 19.

A retractable platform made of telescoping pipes 40 received in openings41 may be attached to the vehicle for carrying cement racks or the like.

The arms or mortar box support 20 may be fixed to the vehicle as shownto carry the mortar box 19 or the arms 20 could be supported in themanner of a conventional high lift so that the power of the machinecould be used to lift the mortar box to a convenient elevation for use.

The foregoing specification sets forth the invention in its preferredpractical forms but the structure shown is capable of modificationwithin a range of equivalents without departing from the invention whichis to be understood is broadly novel as is commensurate with theappended claims.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as follows:
